Default icon height don't work

[fremail]

I put 5 SVG icons with different dimensions (2 icons 19x19 and 3 icons 19x14) and set default icon width and height to 19px and padding to 2px.

In the end of process I got a sprite with original icons sizes (some of them are white):

Maybe my original SVG files cause the problem - I don't know. I'll put several of them here:

19x19 icon:
